Abstract
La présente invention concerne des techniques de déconvolution d'image permettant de déflouter une image présentant un noyau flou. Des statistiques chromatiques localisées obtenues à partir de l'image devant être défloutée sont utilisées en tant que contrainte antérieure pendant une déconvolution. Une couleur de pixel est formulée en tant que combinaison linéaire des deux couleurs les plus présentes dans le voisinage du pixel. Cette opération peut être répétée pour l'ensemble ou une partie des pixels contenus dans une image. Les combinaisons linéaires des pixels sont utilisées en tant qu'antécédents bichromatiques pour déconvoluer l'image floutée. L'antécédent bichromatique est sensible au contenu de l'image et il peut dissocier la netteté des contours de la résistance des contours.
